PIECE#
|
NUMBER
|
backup piece that contains this corrupt block
|
|
FILE#
|
NUMBER
|
Absolute file number of the data file that contains the corrupt blocks
|
|
BLOCK#
|
NUMBER
|
Block number of the first corrupt block in the range of corrupted blocks
|
|
BLOCKS
|
NUMBER
|
Number of corrupted blocks found starting with BLOCK#
|

|
MARKED_CORRUPT
|
VARCHAR2(3)
|
Indicates whether this corruption was not previously detected by the Oracle Database (YES) or the Oracle Database had already discovered this corrupt block and marked it as corrupt (NO). Note that when a corrupt block is encountered in a backup, and was not already marked corrupt by the Oracle Database, then the backup process does not mark the block as corrupt in the production data file. Thus, this field may be YES for the same block in more than one backup set.
|
|
CORRUPTION_TYPE
|
VARCHAR2(9)
|
Type of block corruption in the data file:
-
ALL ZERO - Block header on disk contained only zeros. The block may be valid if it was never filled and if it is in an Oracle7 file. The buffer will be reformatted to the Oracle8 standard for an empty block.
-
FRACTURED - Block header looks reasonable, but the front and back of the block are different versions.
-
CHECKSUM - optional check value shows that the block is not self-consistent. It is impossible to determine exactly why the check value fails, but it probably fails because sectors in the middle of the block are from different versions.
-
CORRUPT - Block is wrongly identified or is not a data block (for example, the data block address is missing)
-
LOGICAL - Block is logically corrupt
-
NOLOGGING - Block does not have redo log entries (for example, NOLOGGING operations on primary database can introduce this type of corruption on a physical standby)

|
CON_ID
|
NUMBER
|
The ID of the container to which the data pertains. Possible values include:
-
0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs.
-
1: This value is used for rows containing data that pertain to only the root
-
n: Where n is the applicable container ID for the rows containing data
